What is a Debian Email Server?
A Debian email server is a software that enables you to send, receive, and manage your email messages. By setting up a Debian email server, you can send and receive emails using your own domain name. This means that you will have full control over your emails and can customize your email server to meet your specific needs.
Setting up a Debian email server can be a challenging task, but with this step-by-step guide, you will be able to set up your own email server in no time.
Step 1: Install Required Packages
The first step to setting up an email server on Debian is to install the necessary packages. These packages include Postfix, Dovecot, and roundcube.
